Managua Targeting
1. Targeting sustainable interventions
An Notenbaert, Tim Robinson, Mark Van Wijk
Impact Pathways and Planning Meeting - Dual Purpose Cattle Value Chain
Managua, 5-9 August
2. Targeting Outputs
Sustainable interventions
• Identified & targeted
• In promising VCs (and sites)
+ tools and approaches
Environmental
impact
Global context
Prioritisation
of interventions .
Economically, socially & environmentally
3. Providing a global context
- For action in the VCs
- For identifying promising VCs
What we’re aiming for
- with CCAFS/CRP2:
- projections of demand, supply, environmental indicators
- Global dialogue around ASF nutrition security
- Prioritisation framework
4. Prioritization of interventions
A few approaches we’d like to test:
- Extrapolate (contact: Tim Robinson)
- Optimisation modeling (contact: Mark Van Wijk)
- System Dynamic Modeling (lead by VCD theme)
Slow track: systems analysis of detailed household data;
systems optimization
Fast track: PRA approaches; ex-ante analysis
5. Ex-ante tool for ranking (policy) alternatives
• Designed for policy interventions (PPLPI) but equally applicable to
technical and systems interventions
• Simple PC-based programme
• Promotes a participatory approach
• Easy to use, well documented
• User Guide
• Reference Manual
• Not data-intensive
• Simple graphic output
• Can evaluate combinations of interventions
• Can be used at a range of levels
1. EXTRAPOLATE
10. Dairy development policy: Uganda
• Promote genetic improvement
• Strengthen delivery of veterinary services
• Provide appropriate extension services
• Improved market infrastructure and information
• Ensure quality control along the chain
• Increase local consumption to build a strong domestic market
• Promote efficiency in the input supply system
• Increased access to credit facilities
Proposed components of policy:
1. EXTRAPOLATE
11. EXTRAPOLATE – analysis tools
Small-medium producers
Pastoralists and agro-pastoralists
Small processors & traders
Poor consumers
Wealthy producers/processors/consumers
1. EXTRAPOLATE
15. Key elements of a pro-poor policy
• Promote genetic improvement
• Strengthen delivery of veterinary services
• Provide appropriate extension services
• Improved market infrastructure and information
• Ensure quality control along the chain
• Increase local consumption to build a strong domestic market
• Promote efficiency in the input supply system
• Increased access to credit facilities
1. EXTRAPOLATE
16. Key elements of a pro-poor policy
• This does NOT mean that genetic improvement and
standards/regulation should be discouraged or dropped from the
policy document
• Rather that when these broad policy outcomes are disaggregated
into their component parts (laws, strategies, institutions etc.) care
needs to be taken to ensure that the poorer producers are not
disadvantaged, and that their needs are also addressed
1. EXTRAPOLATE
17. 2. OPTIMISATION
• Optimization of effect sizes through LP is a standard approach
to do that
• Trade offs between different indicators can be quantified
• Drawbacks:
– All effect sizes need to be quantified accurately
– LP results in single solutions
18. • Therefore: take into account UNCERTAINTY of effects of
interventions on system performance indicators
• By sampling these uncertainty intervals you get
– packages of interventions, rather than single optimal solutions
– Insight in the robustness of the intervention you are proposing
– Insight in key factors that need more accurate quantification

And this you do very often (e.g.
1000s of times) to know the
probability of choosing certain
interventions
1. under which conditions;
2. with which objectives.
23. Prioritization of interventions
All these approaches :
- Based on constraints analysis and best-bet identification in
VCs
- Need for good data and knowledge from the VCs
Short term: identify resource person
Longer term: joint proposal development!
24. Environmental impact assessment
Working on a framework for ex-ante environmental impact
assessment of livestock and fish value chains:
- Pilot study in Dairy VC in East-Africa (BMGF-funded)
- Key dimensions: water, GHG, nutrients
Need for bigger proposal development!

25. CGIAR is a global partnership that unites organizations engaged in research for a food secure future. The CGIAR Research
Program on Livestock and Fish aims to increase the productivity of small-scale livestock and fish systems in sustainable
ways, making meat, milk and fish more available and affordable across the developing world.
